J-V characteristics of the DSSCs composed of the compressed TiO2 NP thin film as photoanode. Under AM 1.5G sunlight. The inset shows (a) open-circuit voltage (VOC), (b) overall photo-to-electron conversion efficiency (η), and (c) short-circuit current density (JSC) as a function of photoanode thickness.
